FWIW, I've run into situations more than once in userspace where I need a
way to properly separate schema and object name. Generally I can make do
using reg* casts and then hitting catalog tables, but it'd be nice if there
was an easier way.
Sure, although I think that's a bit of a separate problem. It's hard
to iterate through a string a character at a time from the SQL level
so that you can handle stuff like the quote_literal() rules. If we
want people to be able to do that easily we need to provide tools to
handle it. But C is actually quite well-suited to such tasks.
Yeah, I wouldn't want to attempt this in SQL; I was saying that a built-in
function to do this would be broadly useful, not just for replicating DROPs.
